Answer

Explanation:

Step1: Recall naming rules for compounds

For binary covalent compounds, prefixes are used to indicate the number of atoms of each element.

Step2: Name the compounds in part 1

a) There seems to be a mis - writing. If it's meant to be a binary compound, we need more context. But if we assume it's a simple naming exercise, we can't name "18fb" as it's not a valid chemical entity. b) "nuzls" is not a valid chemical name. c) For $O_2F_2$, the prefix for two oxygen atoms is "di -" and for two fluorine atoms is also "di -", so the name is dioxygen difluoride.

Step3: Write formulas for part 2

a) Carbon tetrachloride has 1 carbon atom and 4 chlorine atoms, so the formula is $CCl_4$. b) Tetraphosphorus heptabromide has 4 phosphorus atoms (prefix "tetra -") and 7 bromine atoms (prefix "hepta -"), so the formula is $P_4Br_7$. c) There is a mis - spelling. If it's meant to be arsenic disulfide, arsenic is $As$ and sulfur is $S$, and with 1 arsenic and 2 sulfur atoms, the formula is $As_2S$.

Answer:

  1. c) Dioxygen difluoride
  2. a) $CCl_4$ b) $P_4Br_7$ c) $As_2S$ (assuming it's arsenic disulfide)
